I got it yesterday and I enabled the autosave and I beat easy mode this morning so then it amde me play a song during the credits. Then it goes to a black screen so I restart it.. When I try to load it.. It says it has been corrupted. Any advice,knowledge what to do?:wave2:

Possibly the game, or the system.
The disc most likely, my friend had something like that happen on Guitar Hero II, and it no longer works.
Did you buy GH3 used?

No.. I did not

And the freakiest thing was.. When the black screen was on I heard that guitar song like when it is loading but nothing was happening
